Measuring the finite width and unitarity corrections to the phi-omega mixing amplitude
Abstract
It is shown that the phase of phi-omega interference in the reaction e+e- -->pi+ pi- pi0 at energies close to the phi(1020) peak can be calculated in a way that is practically independent of the model of phi-omega mixing. The magnitude of the presently measured interference phase, still of poor accuracy, is in agreement with the predictions based on extending the omega(782) resonance tail from the peak position to the phi mass upon assuming the omega -->rho pi -->3pi model. The calculated omega width at the phi mass is about 200 MeV.
